What is the status of this PR?

[EmilyBourne]

It seems that the status is that currently this test has lists in a class and we don't have the wrapping for that yet. As a result no-one (numba, pythran, pyccel) is capable of handling this example. We can translate but there seems to be an issue with:

• a recursive class method in C
• reference counting in Fortran
• wrapping

Very interesting! It will be nice to have this test once Pyccel is able to handle it.
